Findings in the 9/11 Commission`s final report have added pressure on Homeland Security Undersecretary Asa Hutchinson, a former Republican congressman from Arkansas. Hutchinson, who is in charge of security for the nation`s borders and transportation systems, said the report has made an already stressful job more stressful. The 9/11 Commission has charged Hutchinson with finding a plan to protect the nation`s transportation systems. Hutchinson says his agency is developing new ways to screen passengers, improving explosives screening and working to link various terrorist watch lists. He says his most important accomplishment so far is the installation of a computerized screening system for foreigners known as U-S VISIT, short for the U-S Visitor and Immigrant Status Indicator Technology. Since it started operating at the first of this year, U-S VISIT has screened more than seven million passengers and singled out more than 600 travelers wanted for criminal or immigration violations.
